DRAFT-TONGUE.

Specification of Letters Patent.

Patented May 9, 1916.

Original application filed July 22, 1915, Serial No. 41,273. Divided andthis application filed October 5, 1915. Serial No. 54,213.

To all whom it may concern:

Be it known that I, HERMAN C. MICHEL, a citizen of the United States,residing at Dixie, in the county of \Valla Valla and State ofWashington, have invented certain new and useful Improvements in Draft-Tongues of which the following is a specification.

This application is a division of my application filed July 22, 1915,Serial No. 41,273, the same disclosing an agricultural machine embodyingcertain novel features claimed in said application, and also disclosingan adjustable draft tongue, which latter is the subject matter of thepresent application.

The present invention has for its object to provide a novel and improvedmeans for shifting the draft tongue of an agricultural machine, such asa cultivator, plow, harrow, seeder, etc., so that the machine can beheld on the side of a hill, the shifting means being so constructed andarranged that the tongue may be adjusted while the machine is in motion,and without stopping the same.

In order that the invention may be better understood, reference is hadto the accompanying drawing, in which Figure 1 is a plan view of anagricultural machine showing the application of the invention, and Figs.2, 3 and 1 are sectional details in the lines 2-2, 33 and 44,respectively, of Fig. 1.

Referring specifically to the drawing, 5

denotes the frame of an agricultural machine, mounted on wheels 6, andcarrying earth-working elements 7. The machine here illustrated is acombined Weeder and cultivator; however, it is to be understood that theinvention. is not limited to any particular machine, but may, with equalfacility, be applied to plows, harrows, seeders and all otheragricultural machines.

The draft tongue of the machine is shown at 8, it being carried by ahound frame 9 having yokes 10 at rear ends, said yokes carr ng rollers11. Between these rollers and the yoke branches extends a. shaft 12carried by a front cross bar 13 of the frame 5, and extendingtransversely of said frame. The hound frame is thusslidably mounted onthe shaft 12, so that it may be moved laterally from the center, to putthe draft on either side, and thus hold the machine on a side hill.

The following means are provided for shifting the tongue: At thelongitudinal center of the machine, the cross bar 13 carries a bracket14 which supports a sprocket wheel 15. The yokes 10 are on oppositesides of the sprocket wheel, and they are connected by a chain 16trained over the sprocket wheel. It will therefore be seen that thehound frame 9 is lifted on the shaft 12,in either direction, when thesprocket wheel is turned. The bracket 14 carries a support 17 for theintermediate portion of the shaft 12. The sprocket wheel is operated bya shaft 18 on which it is fast, said shaft extending to the rear end ofthe machine, and being here equipped with an operating crank handle 19,carrying a spring latch 20 engageable with keeper apertures 21 in aplate 22 carried by the rear cross bar 23 of the frame 5. The plate 22also serves as a support for the rear end of the shaft 18, its front endbeing supported by the cross bar 13.

I claim:

In an agricultural machine, a wheeled frame, a transverse shaft mountedat the front end of the frame, a draft device sup port slidably mountedon the shaft, a transverse chain connecting opposite sides of the saidsupport, a sprocket wheel carried by the frame between the sides of thedraft device support, over which sprocket wheel the chain passes, andmeans for o crating the sprocket wheel to shift the dra. t devicesupport along the shaft.

In testimony whereof I afiix my signature in the presence of twowitnesses.

HERMAN ,C. MICHEL.
